It was an interesting bit of film.
One that does NOT ONE DAMN THING to detract from the "actual" Power Rangers.
If our fucked up copyright laws forbid something as simple as this then that whole "To promote the Progress of Science and useful Arts" shit that was intended is totally gone to hell.
If we can't stand on the shoulders of giants (or dudes in tacky suits) and create "new" interpretations, then we've lost the real reason for copyright anyway. I'm not saying that Power Rangers doesn't deserve copyright, but I am saying that reasonable copyright terms should have put it in the public domain by now.
I am currently boycotting all songs from Tom Petty because of his crappy copyright challenge to Sam Smith's "borrowing his song" I mean come on, if we compare every song with every other song and "alter the tempo", and "vary the pitch" then we're screwed. Music reuses all kinds of things all the time. Fuck, soon people will try to copyrighting fucking chords progressions and beats. Yeah Sam Smith's song resembles one of Petty's, but only if you torture it enough. What's next, syllable counts on choruses? That shit was ridiculous.
Copyright has become a farce that no longer does any good for the public. And since thats what it was supposed to be for, I'd say its high time we scrap the whole decrepit edifice of modern copyright law and start over.
